3

What is the chemical equation for photosynthesis?

6CO2+6H2O=C6H12O6+6O2

4

Solar energy is converted to chemical energy in what part of photosynthesis?

Lift reactions

5

In light reactions NADP+ is converted into ___ and ADP is converted into ___ through chemiosmosis. This process is called ____

NADPH, ATP, photophosphorylation

6

During what part of photosynthesis is inorganic carbon from CO2 incorporated into organic compounds through "carbon fixation"?

The Calvin Cycle

7

The reducing power for the Calvin Cycle is provided by ____ and the chemical energy is provided by ___

NADH, ATP

8

Diagram of the transformations taking place

See chapter notes

9

What is found between 380nm and 750nm on the electromagnetic spectrum and why is it important?

Visible light and because it is used for photosynthesis

10

Light can behave as though made up of discrete particles called

Photons

11

Describe the absorption spectrum of chlorophyll a

Absorbs violet and red most. Not green at all

12

Name two accessory pigments

Chlorophyll A and B

13

What happens when a pigment molecule absorbs a photon of light?

One of the the molecules electrons is elevated to an orbital where it has more potential energy

14

Each of the two photosystems is embedded in the

Thylakoid membrane

15

In photosystem II, a photon of light excited a an electron, and as it falls through an electron transport chain, it produces

ATP

16

In photosystem I, a second photon of light re-excites the proton and as it falls through another eleven transport chain, it produces

NADPH

17

Diagram depicting chemiosmosis

See chapter notes

18

Similarities between chloroplasts and mitochondria

2 membranes
Chemiosmosis

19

Differences between chloroplasts and mitochondria

Energy source (sunlight vs sugar)
Chloroplasts are only in plants

20

The Calvin Cycle transforms CO2 into a ____-carbon sugar, which is used to synthesize glucose

Three

21

How is the Calvin cycle similar to the citric cycle?

Regenerate
Starting material

22

How are the Calvin cycle and the citric acid cycle different?

Calvin builds sugar
Krebs breaks down sugar

23

Light energy is converted into chemical energy by what process?

Photosynthesis
